At the fourth attempt, Boris Johnson has secured the general election he wanted. Instead of discussing leaving the European Union, this week Adam Boulton and guests look ahead to the pre-Christmas vote - the first in December for almost a century. They examine the timing, the key policy battlegrounds and discuss the issue of toxicity in British politics as several MPs decide not to stand as candidates. A fascinating but bitter winter campaign lies ahead. Joining Adam this week are the columnist and broadcaster Steve Richards, the Brexit Party MEP Claire Fox and Sky's political correspondent Lewis Goodall.
